Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-100
The AirTAC JSIJ100~125 Adjustable Cylinder JSIJ100X450-100 is a genuine double acting, double rod, adjustable stroke JIS-standard air cylinder with a Ø100mm bore and 450mm stroke, G1/2 air ports and adjustable end cushioning. Its no-tie-rod, hard-anodized profile barrel is more compact than an ISO 15552 cylinder of the same bore — a space-saver on tight machines.

About the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-100
The hard-anodized aluminum barrel makes it shorter and more compact than a same-bore ISO 15552 unit. Air connects via a G1/2 port.
The external adjuster lets you shorten the extend stroke on-site by up to 100 mm, giving a usable range of 350-450 mm while the retract end stays fixed. You can fine-tune the end position without swapping the cylinder. This SKU lacks a magnet, so it cannot take a CMSE or DMSE sensor. The 33 mm adjustable air cushions at both ends only decelerate the piston near stroke end; they do not hold the load on air loss, so fit an external rod lock or pilot-operated check valve for vertical holding.

Theoretical Output Force (Ø100mm)
| Pressure | Push force | Pull force |
|---|---|---|
| 0.5 MPa | 3525 N | 3525 N |

JSIJ is double-rod: the rear rod that carries the stroke adjuster passes through the rear cover, so both piston faces lose rod area. Push is shown at the annular-area value (conservative).

Where the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-100 Is Used
Pallet Divertor Tuning
Dial in the exact 350-450 mm push distance to deflect heavy pallets on a transfer line without re-mounting hardware.
Press Pin Setting
Set precise pin insertion depths on-site, shortening the extend stroke from 450 mm down to 350 mm as needed.
Is the Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-100 the Right Cylinder?
The 100 mm hits a sweet spot for mid-heavy actuation. The 100 mm adjustable window is ideal for sharing a spare across stroke variants or dialing in final end positions on-site. Mounting options include FA, LB, TC, TCM1, and TCM2. Because this is a 450 mm stroke, you must support the load with external guides to prevent rod bending and side-load damage. As a non-magnet SKU, it cannot accept position sensors.
Quick checklist
- ✓ Required force at your working pressure
- ✓ Stroke and mounting space
- ✓ Port/thread type (PT / G / NPT)
- ✓ Magnet (-S) for sensors?
- ✓ Side load — consider a guided cylinder
Installation & Maintenance Notes
- check Use clean air filtered to 40µm or finer.
- check Keep within 0.15 – 1.0 MPa operating pressure.
- check Avoid side load on the piston rod.
- check Set cushions to minimum, then release gradually.
- check Use correct mounting accessory (LB/FA/FB/CA/CB/TC).
- check Installation by qualified personnel per AirTAC docs.
Airtac JSIJ100~125 Adjustable Cylinder JSIJ100X450-100 FAQ
At 0.5 MPa it pushes 3927 N and pulls 3574 N. At 0.7 MPa it pushes 5497 N and pulls 5003 N. The theoretical maximum force is 801 kgf at 1.0 MPa. The G1/2 port feeds the 32 mm rod.
The nominal 450 mm extend stroke is the maximum. The external stop screw lets you shorten that extend stroke on-site by up to 100 mm, yielding a usable 350-450 mm range. The retract end remains fixed.
